i i. lnnnmfron.

To vall whom t may comerm Be Iit known thatzLJoHN A. Mmnnma citizen. ofthe .United States, andy al, resident of Tarrytown, in the county of Westchester and AState ofNew York, have made and invented certain new anduseful Improvements in Radiators, of which ,the following is a specification. y

My invention relates to an improvement in radiators, such as areusedonautomobiles', the object ofthesame bei vice of this character whic :shall presentas much radiating surface as possible tothe air, 'which' shall be simple and economicalto construct, and cheap to manufacture, and which shall be so formed andgassembled that the water will be caused-to travel through the radiating pipes in its passage from the top of the radlator wherein it enters, to the lower art or portion of the same out of which'it Hows, thereby a-ifording ample time and means for its effective coohng.

With these and other ends in v1ew, the invention consists in certain novel features of construction and combinations of parts, as will be'hereinafter fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view partly in sectlon and partly 1n elevation of my improved radiator. .Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1. Fig. 3 is a sectional view taken on.

ator illustrated in Fig. 1, but showing the inlets located in the slde tubes. Fig. 8 is a view of the radiator illustrated in Fig. 6, but showing the inlet located in the vertical central tube.

Referring to the drawings, it will be seen-al that the radiator in its one form consists the upper horizontal chamber 7, the lower chamber 8, and the three vertical tubes 9,

10, 11, the vertical side tubes 9, 10, formingthe outer sides of the device, communicatin at their upper ends with the chamber 7, and the central vertical tube 11 communicating at its lower end with the lower chamber 8.

to, provide a de Specincation of Letterslatent. Patented 0ct.,19, 1909. y application med I uiy '13, 1909. serial ms. sowas.

The upper -chamber is rovided with the in- {et 12, andthe lower c amber with lthe outet 13. Y

, Connecting the lvertical tube 9 and central vertical tube 11, and also connecting. the vertical tube 10 and central vertical tube 11, are the pipes 14, the inner andouter ends thereof i being open, and soldered or otherwise tightly secured to the wall of the tubes 9, 10, and also tothewallsof the tubell, as illustrated in Fig. 4, the. chambers 7, 8, and also tubes 9, 10 and v11, aswell as the pipes 14, being preferably formed of'sheet metal.

4In order ltoassist holding the pipes 14.

in theirproper relative position', I insert be'- tween them, braces of supports 15, preferably formed as illustratedin Fig. `5, that is, of angular perforated sheet metal, the outer corners or edges being soldered to the ipes if desired, to prevent detachment there om. In ractice, the water enters the openin 12, lling the chamber 7, whereu on 1t Wil How into the tubes 9 and 10 andt rough the.

pipes 14 into the central vertical tube 11, and out of the latter into the lower chamber 8, from which it issues through the outlet opening 13. If desired, however, the radiator may be constructed as illustrated in Fig. 6, that is, the upper horizontal chamber 16 may be formed to communicate with the central vertical tube 17, and the side tubes 18, 19, to communicate with the lower chamber 20. When so formed, the water entering through the inlet opening 21 and lilling the chamber 16, will flow into the central tube 17, through the pipes 22 into the side tubes 18, 19, and into the lower chamber 20, from which it issues through the outlet opening 23. In each instance, however, it will be seen that the water `flowing into the upper chamber will be caused to flow through the pipes in order to reach the lower chamber, thereby affording the water ample time to radiate its heat through the walls of said pipes before passout of the lower chamber.

not absolutely essential thatthe inlet be lo- P- 'gcated in the upper chamber, as illustrated in igs. 1 and 6 of the drawings, but may be located as illustrated in Fig.'7, that is, the water `mayenter the side tubes 9 and 10 at 24--25, in which event the water will circulate through these tubes and upper chamber some point in their length, as illustrated at vertical tube 17, as illustrated at 26. In such` instance, the water will circulate in this central tube 17 and upper chamber 16, through the pipes 22, side tubes 182 19, and lower chamber 20, from which it w11l issue through the outlet opening 23, as before described.

Having 4fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A radiator ofthe character described comprising upper and lower chambers, a central vertical tube, side tubes, and pipes connecting said vertical tube and side tubes through which pipes said water passes in travellng from the upper chamber to said lower chamber, substantially as described.

2. A radiator of the character described, comprising upper and lower chambers, a central vertical tube communicating with said `and then into the lower chamber, substan-` tially as described.

3. A radiator of the character described, comprising upper and lower chambers, side tubes, a central tube, ipes communieatingl at one end to said si e tubes, and at theiropposite ends to said central tube, and perforated angular metri located between said pipes for assisting in retaining the latter in their roper relative positions, substantially as escribed.

Signed at New York, borough of Manhattan, 1n the county of New York, and State of New York, this 8th day of July, A. D. 1909.
